AP1 s2000 / Megan Track Series Coilovers.

I KNOW YOU CANT DRIVE SLAMMED AND HAVE A SMOOTH RIDE, but please mind my question.

-Ive been driving on the Track series coils and struts (12kg's front and back with AGGRESSIVE dampening) for a couple years now. Its great on perfectly smooth roads but as this is going to be my daily driver for the forseable future, Id like to soften up the ride and still stay as close to as low as I am (pretty slammed). Its getting to be unbearably uncomfortable.

My question is this - I am considering replacing them with 8kg, or 10kg, and new struts as well accordingly. In your opinion, WILL 8kg be too soft for a lowered s2k driving on normal city streets?

Any help is appreciated and thanks in advance for any help offered.

 

I can't say whether 8 kg/mm will work or not... a pic of how low your car is might help. However, 8 kg/mm = 450 lb/in. If 450 lb/in springs can't keep your car off the bump stops for normal daily driving duties, then the car is too low. You will have 2 choices - raise the car up or keep the 12 kg/mm springs.

 

You should email Megan to see if those shocks can handle the rates that you want to switch to. Going from 12k to 10k shouldn't be a big deal. Keyword is shouldn't, but you never know. Also apply everything else that Pat has mentioned.

 

my buddy has an ap2 with megan track coilovers and it is extremely comfortable, surprisingly, even over new england roads. is it an ap1 vs ap2 thing?

 

cool, will you ask if he has the street, EZ street, or Track series? I think Im going with EZ street, the rubber mounts instead of pillowball uppers will be much softer im thinking, and 10kg's plus softer valved shocks should be just the ticket.

Ps... Raise it? hahahahahahahahahahahahahahahahahaha.

 

or dont buy crappy coilovers made in taiwan and drive it lowered to douche status.

 

drive on them then talk. Im so sick of you name brand people, there are companies trying hard to make quality products, if you never try you'll never know. I just had a track setup driving on the streets for years and its been perfect, Just rough. its a stiff setup.

That being said, A) Ill drive as low as I want, B) we're in the SUSPENSION forum, and C) lower your car and maybe you'll get as many broken necks as I do before you get all e-thug, I was just joking. Im guessing if you had any input reguarding strut stiffness and spring rates you wouldve left it.

Ive decided on 10kg's and a lil softer struts, Its better to over dampen then under dampen so Im just gonna take it down a little and see how it feels, they offer all kinds of replacement struts and springs anyway, Ill update with some feedback.

 

they're definitely the track series. the jack points basically touch the ground too.

 

You asked about 8 kg springs, which IMHO are already stiff as F for street use. And I said if those can't keep the car off the bumpstops then the car is too damn low. Yeah, you drive it as low as you want, but the lower you are, the stiffer the springs have to be unless you just want to start breaking stuff, while jarring your brains out in the process.

 

If we're talking about women, this statement works perfectly.
If we're talking about cars, then it is wrong on multiple levels.

"Dampen" is to make wet. Shocks damp the suspension.
Most people prefer under damped to over damped. Most stock cars are slightly under damped for this reason.

Anyone know the motion ratio of the AP1 S2k? I won't even try and comment on spring rates without it.

 

From the diagram it looks like the front motion ratio is somewhere between 1.15 to 1.25 or so. The shocks mount very close to the knuckle's lower ball joint.

 

I daily on 400 lbs/in spring rates (7.1 kg/mm) on my DC2.

With the heavier S2k and that assumed MR, 8k would sound reasonable for a lowered daily. 12k for slammed sounds reasonable too.

Of course, that also assumes high driver tolerance of a stiff suspension and quality shocks to control it all. I would also assume that Megan brand "track" oriented shocks are not what I would consider quality shocks for street use, as I would (again) assume that they have a very linear compression damping curve and high overall damping forces, which can be desirable on track but a pain on the street.
